Shop page layout issue

Suggest you deactivate WP-Super-Cache until you resolve the problem, and delete all cached content.

It looks like there is a css corruption or conflict somewhere, so you need to narrow it down to the element which is responsible.

Deactivate all your plugins except WooCommerce. If the page now displays correctly, reactive your plugins one by one to try to identify which plugin is causing the conflict.

If the page still displays incorrectly with all plugins deactivated, then it is a theme issue and you should seek support from the vendor. They are best placed to provide theme support and support is included with the purchase price.
